Single-File STF

Intel® Trace Collector can save the trace data in the single-file STF format. This format is selected by specifying the
LOGFILE-FORMAT STFSINGLE
configuration option, and it causes all the component files of an STF trace to be combined into one file with the extension
.single.stf
. The logical structure is preserved. The drawback of the single-file STF format is that no I/O parallelism can be exploited when writing the tracefile.
Reading it for analysis with Intel® Trace Analyzer is only marginally slower than the normal STF format, unless the operating system imposes a performance penalty on parallel read accesses to the same file.
